    创始人2025-01-09

    TDXL-811M is a GPS dual-satellite active built-in helical antenna that features multi-arm helical technical design, supporting the reception of dual-frequency satellite navigation signals from the GPS L1 and L5 bands. It could meet the requirements of high-precision measurement and is widely applied in portable equipment, UAVs and other high-precision navigation and positioning locations.

    1、Using multi-arm helical technique, the antenna enables the right circular polarization and phase center performance, as well as minimizes the impact of measuring error;

    2、The antenna unit offers high gain and minimal gain roll-off, providing excellent reception of low elevation satellite signals and ensuring normal reception in severely obscured locations.

    3、Using multi-arm multi-feed zero phase center technique, the antenna enables the RHCP and phase center stability.

    4、High LNA gain, low noise figure.

    5、Strong capacity in filter out-of-band rejection and antenna anti-jamming.

    6、Compact size, lightweight, portable and easy to install.
